Synopsis

In the distant past, a powerful race called the Forerunners fought an alien parasite known as the Flood. The Flood, which spread through infestation of sentient life, overran much of the Milky Way Galaxy. One of the races affected was humanity, who came into conflict with the Forerunners as a result. Exhausted by their war and after having explored all other options, the Forerunners conceived a weapon of last resort to combat the Flood, called the Halo Array. Using an installation known as the Ark, they built large ring-shaped megastructures known as Halos. The Halo Array, when activated, would destroy all sentient life in the galaxy – depriving the Flood of their food, after which samples of the lost lifeforms would be reseeded. Delaying as long as they could, the Forerunners activated the rings and disappeared.[15]
Nearly a hundred thousand years later, in the 26th century, humanity – under the auspices of the United Nations Space Command, or UNSC – colonize many worlds thanks to the development of faster-than-light "slipspace" travel. Tensions escalate between the older and more stable "Inner Colonies" and the newer, remote "Outer Colonies", leading to civil war. The UNSC sponsors the Spartan-II program to create an elite group of enhanced supersoldiers, whose purpose is to suppress the rebellions covertly.[16] In the year 2525, human worlds come under attack by a theocratic alliance of alien races known as the Covenant. The Covenant leadership declares humanity heretics and an affront to their gods – the Forerunners – and begins a holy war of genocide. The Covenant's superior technology and numbers prove decisive advantages; though effective, the Spartans are too few in number to turn the tide of battle in humanity's favor.
In 2552, the Covenant arrive at the UNSC's last major stronghold beyond Earth – the planet Reach, in orbit of Epsilon Eridani – and launch an invasion of the planet. The last Spartans and UNSC military are unable to stop the Covenant from bombarding the planet. The UNSC Navy suffers devastating losses, and every Spartan but their leader, player character Master Chief John-117, is believed to be lost in action. Following directives to avoid leading the Covenant to Earth, Cortana, the AI aboard the fleeing UNSC ship Pillar of Autumn, selects random coordinates that lead the ship to a Halo ring, Installation 04. These events form the backdrop to the first game in the series, Halo: Combat Evolved.
Over the course of the game, the Covenant pursue, damaging the Autumn and leading its crew to wage a guerrilla war on the ring's surface. The Covenant accidentally release Flood imprisoned on the ring; to nullify the threat, the ring's AI caretaker, 343 Guilty Spark, enlists the help of the Master Chief in activating Halo. Cortana reveals that Halo's activation would mean their own destruction. Therefore, she and the Master Chief chose to detonate Autumn's engines, destroying Halo and preventing the escape of the Flood.
Between the events of the first game and Halo 2, the Chief and a few other survivors return to Earth, warning of an impending Covenant attack; this attack forms the first mission of the game. Meanwhile, the Covenant, unaware of the destructive nature of the rings, attempt to fire another ring, Installation 05, to fulfill their religious prophecy[17] and to do so launch an attack on Earth. Helping the Chief defend Earth are Sergeant Avery Johnson and Commander Miranda Keyes. The Covenant Elites learn the truth about the rings and are led by a former Elite commander named the Arbiter (also a player character) to join forces with humanity to stop the firing of the ring. Though they are successful, the unexpected shutdown of the installation triggers a fail-safe protocol, priming all the rings for firing from the Ark.[18]
Halo 3 picks up immediately after, with the Covenant's leader, the High Prophet of Truth, and the remaining loyalist Covenant uncovering a portal to the Ark on Earth. A battle rages on Earth between human forces, the Covenant, and a Flood-infected army. Eventually, the Covenant is repulsed and flees through a slipspace portal, and the Flood is purged from Earth, though much of Africa has been devastated in the battle.
Chief, Arbiter, Elites, Johnson, Keyes, and U.N.S.C. troops follow the Covenant "Prophet of Truth" through the portal, joined by 343 Guilty Spark, who aids the Chief as he has no function to fulfill after the destruction of his ringworld. During the ensuing battle between humans, Covenant, and the Flood on the Ark, Johnson is captured by Truth to activate the Halo rings. Keyes tries to intervene, but is killed. Master Chief and the Arbiter, aided by the Flood, kill Truth and rescue Johnson. After finding out that the Ark is constructing a replacement for Guilty Spark's Halo ring, Installation 09, Master Chief decides to fire the unstable Halo, destroying both the Flood and the Ark. After finding out about their plan, Guilty Spark kills Johnson and tries to kill Master Chief, but Master Chief destroys Guilty Spark and activates the Halo. Master Chief and the Arbiter escape on the UNSC frigate Forward Unto Dawn, but the slipspace portal closes with Master Chief's half trapped in space. After a memorial service on Earth for the victims of the Human-Covenant war, the Arbiter and his Elite brethren depart for their home planet. The rear half of Forward Unto Dawn floats in deep space. Cortana activates a distress beacon and the Chief goes into hibernation.
Four years later, the Chief and Cortana awake to find they are being attacked by an Ex-Covenant splinter faction lead by Jul 'Mdama(Halo 4). Caught in an artificial gravity well, they are pulled into the artificial Forerunner planet of Requiem, along with the UNSC ship Infinity.[19][20] Master Chief, fighting Jul 'Mdama's Covenant faction and robotic warriors called Prometheans, unwittingly releases a hostile Forerunner warrior called "The Didact" from imprisonment. While seeking a way to combat the Didact, Cortana reveals that she is becoming "rampant" (an inevitable state leading to insanity that AIs reach when their knowledge base finally becomes too large). Master Chief is eventually contacted by a personality construct of a Forerunner called the Librarian (The Didact's Wife), who tells him about the Didact: during the crisis with the Flood, the Didact tried to use a device called the Composer to transform humanity into Prometheans. He did this because he needed soldiers that were immune to Flood Infection. His own race then imprisoned him along with the Forerunner soldiers and humans he had already converted. The Composer was hidden. After the Didact leaves Requiem and retrieves the Composer, Cortana and the Master Chief pursue him to Earth. Although the Didact is able to fire the Composer at North America, digitizing over seven million people, the Master Chief and Cortana are eventually able to cast the hateful Forerunner into a slipspace portal. They then destroy the Composer and the Didact's ship with a nuclear device. Cortana sacrifices herself to save the Master Chief from the resultant explosion. Master Chief is later found floating among the rubble, and taken back to Infinity.
Halo 5: Guardians begins eight months later. Blue Team — consisting of four of the five remaining Spartan-II's (Master Chief, Fred-104, Kelly-87 and Linda-58), receives signals from Cortana indicating that she has survived her "death" by taking advantage of Forerunner AI technology. The Chief, disobeying direct orders, travels to the planet Genesis to reunite with her. Another fireteam known as Fireteam Osiris, a group of Spartans from the competing Spartan-IV program, are dispatched to apprehend him. This journey takes them to several places around the galaxy, including the Elite homeworld of Sanghelios, where the Arbiter leads an offensive against the final remnants of Jul 'Mdama's Ex-Covenant faction. As they travel, Osiris discover that Cortana is activating ancient Forerunner constructs — the eponymous Guardians — with which she plans to impose permanent galactic peace on pain of death. She holds the Master Chief's team captive in a Cryptum to force them into meditative hibernation, and while Fireteam Osiris are able to rescue them, they are not able to stop Cortana from executing her plan, disabling most contemporary technology in the galaxy by way of the Guardians, and thus bringing all remaining sentient species under her aegis. As the game ends, Blue Team, Fireteam Osiris and the Arbiter regroup on Sanghelios to plan their resistance.
